It is soluble in water and dilute nitric acid. Basic nitrates are formed in when alkali is added to a solution. Pb 2 (OH) 2 (NO 3) 2 is the predominant species formed at low pH. At higher pH Pb 6 (OH) 5 (NO 3) is formed. [17] The cation [Pb 6 O(OH) 6] 4+ is unusual in having an oxide ion inside a cluster of 3 face-sharing PbO 4 tetrahedra. [18]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Lead(II) sulfate is poorly soluble, as can be seen in the following diagram showing addition of SO 2− 4 to a solution containing 0.1 M of Pb 2+. The pH of the solution is 4.5, as above that, Pb 2+ concentration can never reach 0.1 M due to the formation of Pb(OH) 2. Observe that Pb 2+ solubility drops 10,000 fold as SO 2− 4 reaches 0.1 M.
Pb(NO 3) 2 (aq) + KIO 3 (aq) → KNO 3 (aq) + Pb(IO 3) 2 (s) Industrial mass production methods use a less precise method due to higher quantities of reactants. Many other group 1 elements can be used in place of potassium to add iodate to the reaction due to solubility of group 1 element iodates.

2 is commonly synthesized via a precipitation reaction between potassium iodide KI and lead(II) nitrate Pb (NO 3) 2 in water solution: Pb(NO 3) 2 + 2 KI → PbI 2 + 2 KNO 3. While the potassium nitrate KNO 3 is soluble, the lead iodide PbI 2 is nearly insoluble at room temperature, and thus precipitates out. [17] Other soluble compounds ...
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
